Factors Influencing Sanitation Conditions

Factors Influencing Sanitation Conditions ABSTRACT This thesis examines the socio-cultural and demographic factors influencing sanitation conditions, identifies the presence of Escherichia coli in household drinking water samples and investigates prevalence of diarrhoea among infants. It is based on questionnaire interviews of 120 household heads and 77 caretakers of young children below the age of 5years, direct observation of clues of household sanitation practice as well as analyses of household water samples in six surrounding communities in Bogoso. Data collected was analysed using SPSS and the Pearson Product Moment Correlation Value(R) technique. The findings revealed that the sanitation condition of households improved with high educational attainment and ageing household heads. On the contrary, sanitation deteriorated with overcrowding in the household. Furthermore, in houses where the religion of the head of household was Traditional, sanitation was superior to those of a Christian head and this household also had better sa nitary conditions than that with a Moslem head of household. Water quality analysis, indicated that 27 samples out of the 30 representing 90% tested negative for E. Coli bacteria whilst 17(56.7%) samples had acceptable levels of total Escherichia coli. Finally, it was found out that diarrhoea among infants were highly prevalent since 47 (61.04%) out of the 77 child minders admitted their wards had a bout with infant diarrhoea. Massive infrastructural development, supported by behavioural change education focussing on proper usage of sanitary facilities is urgently needed in these communities to reduce the incidence of public health diseases. Intensive health education could also prove vital and such programs must target young heads of household, households with large family size and households whose heads are Christians and Moslems. CHAPTER ONE INTRODUCTION BACKGROUND TO THE STUDY Efforts to assuage poverty cannot be complete if access to good water and sanitation systems are not part. In 2000, 189 nations adopted the United Nations Millennium Declaration, and from that, the Millennium Development Goals were made. Goal 4, which aims at reducing child mortality by two thirds for children under five, is the focus of this study. Clean water and sanitation considerably lessen water- linked diseases which kill thousands of children every day (United Nations, 2006). According to the World Health Organization (2004), 1.1 billion people lacked access to an enhanced water supply in 2002, and 2.3 billion people got poorly from diseases caused by unhygienic water. Each year 1.8 million people pass away from diarrhoea diseases, and 90% of these deaths are of children under five years (WHO, 2004). Ghana Water and Sewerage Corporation (GWSC) had traditionally been the major stakeholder in the provision of safe water and sanitation facilities. Since the 1960s the GWSC has focussed chiefly on urban areas at the peril of rural areas and thus, rural communities in the Wassa West District are no exception. According to the Ghana 2003 Core Welfare Indicators Questionnaire (CWIQ II) Survey Report (GSS, 2005), roughly 78% of all households in the Tamale Metropolis, 97 percent in Accra, 86% in Kumasi and 94% in Sekondi-Takoradi own pipe-borne water. Once more, the report show that a few households do not own any toilet facilities and depend on the bush for their toilet needs, that is 2.1%, 7.3%, and 5% for Accra, Kumasi, and Sekondi-Takoradi correspondingly. Access to safe sanitation, improved water and improved waste disposal systems is more of an urban than rural occurrence. In the rural poor households, only 9.2% have safe sanitation, 21.1% use improved waste disposal method and 63.0 % have access to improved water. The major diseases prevalent in Ghana are malaria, yellow fever, schistosomiasis (bilharzias), typhoid and diarrhea. Diarrhea is of precise concern since it has been recognized as the second most universal disease treated at clinics and one of the major contributors to infant mortality (UNICEF, 2004). The infant mortality rate currently stands at about 55 deaths per 1,000 live births (CIA, 2006). The Wassa West District of Ghana has seen an improvement in water and sanitation facilities during the last decade. Most of the development projects in the district are sponsored by the mining companies, individuals and some non-governmental organisations (NGOs). Between 2002 and 2008, Goldfields Tarkwa Mine constructed 118 new hand dug wells (77 of which were fitted with hand pumps) and refurbished 48 wells in poor condition. Also, a total of 44 modern style public water closets, were constructed in their catchment areas. The company also donated 19 large refuse collection containers to the District Assembly and built 6 new nurses quarters. The Tarkwa Mine has so far spent 10.5million US dollars of which 26% went into health, water and sanitation projects, 24% into agricultural development, 31% into formal education and the remaining went into other projects like roads and community centre construction ( GGL, 2008). Golden Star Resources (consist of Bogoso/Prestea Mine and Wassa Min e at Damang) also established the community development department in 2005 and has since invested 800 thousand US dollars. Their projects include 22 Acqua-Privy toilets, 10 hand dug wells (all fitted with hand pumps) and supplied potable water to villages with their tanker trucks (BGL, 2007). Other development partners complimenting the efforts of the central government include NGOs WACAM, Care International and Friends of the Nation (FON). WACAM is an environmentally based NGO which monitors water pollution by large scale mining companies. They have sponsored about 10 hand dug wells for villages in the district. Care International sponsors hygiene and reproductive health programmes in schools and on radio. They have also donated a couple of motor bicycles to public health workers in the district who travel to villages. The aims of all these projects were to improve hygiene and sanitation so as to reduce disease transmission. Despite efforts by the development partners, water supply and sanitation related diseases are highly prevalent in the district. Data obtained from the Public and Environmental Health Department of the Ministry of Health (M.O.H., 2008) showed that the top ten most prevalent diseases in the district include malaria, acute respiratory infections, skin diseases and diarrhoea. The others are acute eye infection, rheumatism, dental carries, hypertension, pregnancy related complications and home/occupational accidents. A lot more illnesses occur but on a lower scale and these include intestinal worms, coughs and typhoid fever. A complete data on the top ten diseases prevalent in the district is attached as Appendix D but below is a selection of the illnesses that directly result from bad water and sanitation practices. The number of malaria cases decreased from 350 in 2006 to 300 cases per 1000 population in 2008. Despite the decrease, the values involved are still quite high. The incidence of diarrhoea among infants and acute respiratory infection remained 30 and 60 cases per 1,000 populations respectively. This can be attributed to several reasons, including population boom, lack of uninterrupted services and inadequate functioning facilities. In fact, according to the World Health Organization (WHO, 2004), an estimated 90% of all incidence of diarrhoea among infants can be blamed on inadequate sanitation and unclean water. For example, in a study of 11 countries in Sub-Saharan Africa, only between 35-80% of water systems were operational in the rural areas (Sutton, 2004). Another survey in South Africa recognized that over 70% of the boreholes in the Eastern Cape were not working (Mackintosh and Colvin, 2003). Further examples of sanitation systems in bad condition have also been acknowledged in rural Ghana, where nearly 40% of latrines put up due to the support of a sanitation program were uncompleted or not used (Rodgers et al., 2007). The author had a personal communication with the District Environmental Officer and he estimated that, approximately there are 224 public toilets, 560 hand dug wells, 1,255 public standpipes and 3 well managed waste disposal sites in the district. According to the 2006 projection, the population of the district is expected to reach 295,753 by the end of the year 2009 (WWDA, 2006). Development partners in the past have concentrated their efforts on facilities provision only. They have not looked well at the possible causes of the persistence of disease transmission despite the effort they are making. Relationships between households socio cultural demographic factors and peoples behaviour with respect to the practice of hygiene could prove an essential lead to the solution of the problem. The fact is, merely providing a water closet does not guarantee that it could be adopted by the people and used well to reduce disease transmission. Epidemiological investigations have revealed that even in dearth supply of latrines, diarrhoeal morbidity can be reduced with the implementation of improved hygiene behaviours (IRC, 2001: Morgan, 1990). Access to waste disposal systems, their regular, consistent and hygienic use and adoption of other hygienic behavioural practices that block the transmission of diseases are the most important factors. In quite a lot of studies fro m different countries, the advancement of personal and domestic hygiene accounted for a decline in diarrhoeal morbidity (Henry and Rahim, 1990). The World Bank, (2003) identifies the demographic characteristics of the household including education of members, occupation, size and composition as influencing the willingness of the household to use an improved water supply and sanitation system. Education, especially for females results in well spaced child birth, greater ability of parents to give better health care which in turn contribute to reduced mortality rates among children under 5years (Grant, 1995). In a study into water resource scarcity in coastal Ghana, Hunter (2004) identified a valid association between household size, the presence of young children and the gender of the household head. It was noted that, female heads were less likely to collect water in larger households. Furthermore, increasing number of young children present increased the odds of female head/spouse being the household water collector. Cultural issues play active part in hygiene and sanitation behaviour especially among members of rural communities. For example, women are hardly seen urinating in public due to a perceived shame in the act but men can be left alone if found doing it. Also, the act of defecation publicly is generally unacceptable except when infants and young children are involved. The reason is that the faeces from young people are allegedly free from pathogens and less offensive (Drangert, 2004). Ismails (1999) work on nutritional assessment in Africa, detected that peoples demographic features, socioeconomic and access to basic social services such as food, water and electricity correlate significantly to their health and nutrition status. Specifically, factors such as age, gender, township status and ethnicity, which are basic to demography, can play a role in the quality of life especially of the elderly. This research assessed peoples practice of personal hygiene in Bogoso and surrounding villages. It also identified the common bacteria present in household stored water sources. Furthermore, the research identified the relationships between some socio-cultural demographic factors of households and the sanitation practice of its members. THE PROBLEM STATEMENT The Wassa West District in the Western Region is home to six large scale mining companies and hundreds of small scale and illegal mining units. Towns and villages in the district have been affected by mining, forestry and agricultural activities for over 120 years (BGL EIS, 2005). Because of this development, the local environment has been subjected to varying degrees of degradation. For example, water quality analysis carried out in 1989 by the former Canadian Bogoso Resources (CBR) showed that water samples had Total coliform bacteria in excess of 16 colonies per 100ml (BGL EIS,2005). Most of the water and sanitation programs executed in the district exerted little positive impact and thus, diarrhoeal diseases are still very high in the towns and villages (See Appendix D on page 80). However, in order to solve any problem it is important to appreciate the issues that contribute to it; after all, identifying the problem in itself is said to be a solution in disguise. Numerous health impact research have evidently recognized that the upgrading of water supply and sanitation alone is generally required but not adequate to attain broad health effects if personal and domestic hygiene are not given equivalent prominence (Scherlenlieb, 2003). The troubles of scarce water and safe sanitation provisions in developing countries have previously been dealt with by researchers for quite some time. However, until recent times they were mostly considered as technical and/or economic problems. Even rural water and sanitation issues are repeatedly dealt with from an entirely engineering point of view, with only a simple reference to social or demographic aspects. Therefore, relatively not much is proven how the socio-cultural demographic influences impinge on hygiene behaviour which in turn influences the transmission of diseases. The relationship between household socio cultural factors and the sanitation conditions of households in the Wassa West District especially the Bogoso Rural Council area has not been systematically documented or there is inadequate research that investigates such relationship. THE RESEARCH QUESTIONS The following research questions were posed to help address the objectives; Why are the several sanitation intervention projects failing to achieve desired results? Why is the prevalence of malaria and diarrhea diseases so high in the district? What types of common bacteria are prevalent in the stored drinking water of households? OBJECTIVES The main aim of this research was to investigate peoples awareness and practice of personal hygiene, access to quality water and sanitation and the possible causes of diarrhoeal diseases and suggest ways to reduce the incidence of diseases in the community. The specific objectives were; To assess the quality of stored household drinking water To establish the extent to which sanitation behaviour is affected by household socio-cultural demographic factors like age and education level of the head. To investigate the occurrence of diarrhoea among young children (0-59 months old) in the households. To identify and recommend good intervention methods to eliminate or reduce the outbreak of diseases and improve sanitation. HYPOTHESIS In addition to the above objectives, the following hypotheses were tested; Occurrence of infant diarrhoea in the household is independent on the educational attainment of child caretakers. There is no relationship between households background factors and the sanitation conditions of the household. CHAPTER TWO LITERATURE REVIEW In this chapter, various literature related to the subject matter of study are reviewed. Areas covered are sanitation, hygiene, water quality and diarrhoeal diseases. Theories and models the study contributed to include USAIDs Sanitation Improvement Framework, the F diagram by Wagner and Lanois and the theory of Social learning. SANITATION Until recently, policies of many countries have focused on access to latrines by households as a principal indicator of sanitation coverage, although of late there has been a change and an expansion in understanding the term sanitation. Sanitation can best be defined as the way of collecting and disposing of excreta and community liquid waste in a germ-free way so as not to risk the health of persons or the community as a whole (WEDC, 1998). Ideally, sanitation should end in the seclusion or destruction of pathogenic material and, hence, a breach in the transmission pathway. The transmission pathways are well known and are potted and simplified in the F diagram (Wagner and Lanois 1958) shown below by figure 3.1. The more paths that can be blocked, the more useful a health and sanitation intervention program will be. It may be mentioned that the health impact indicators of sanitation programmes are not easy to define and measure, particularly in the short run. Therefore, it seems more reasonable to look at sanitation as a package of services and actions which taken together can have some bearing on the health of a person and health status in a community. According to IRC (2001:0), issues that need to be addressed when assessing sanitation would include: How complete the sanitation programme is in addressing major risks for transmitting sanitation-related diseases; Whether the sanitation programme adopted a demand driven approach, through greater peoples participation, or supply driven approach, through heavy subsidy; Whether it allows adjustment to peoples varying needs and payment; If the programme leads to measurably improved practices by the majority of men and women, boys and girls; If it is environmentally friendly. That is; if it does not increase or create new environmental hazards (IRC, 2001) Sanitation is a key determinant of both fairness in society and societys ability to maintain itself. If the sanitation challenges described above cannot be met, we will not be able to provide for the needs of the present generation without hindering that of future generations. Thus, sanitation approaches must be resource minded, not waste minded. HYGIENE Hygiene is the discipline of health and its safeguarding (Dorland, 1997). Health is the capacity to function efficiently within ones surroundings. Our health as individuals depends on the healthfulness of our environment. A healthful environment, devoid of risky substances allows the individual to attain complete physical, emotional and social potential. Hygiene is articulated in the efforts of an individual to safeguard, sustain and enhance health status (Anderson and Langton, 1961). Measures of hygiene are vital in the fight against diarrhoeal diseases, the major fatal disease of the young in developing countries (Hamburg, 1987). The most successful interventions against diarrhoeal diseases are those that break off the transmission of contagious agents at home. Personal and domestic hygiene can be enhanced with such trouble-free actions like ordinary use of water in adequate quantity for hand washing, bathing, laundering and cleaning of cooking and eating utensils; regular washing and change of clothes; eating healthy and clean foods and appropriate disposal of solid and liquid waste. Diarrheal Dise ases Diarrhoea can be defined in absolute or relative terms based on either the rate of recurrence of bowel movements or the constancy (or looseness) of stools (Kendall, 1996). Absolute diarrhoea is having more bowel movements than normal. Relative diarrhoea is defined based on the consistency of stool. Thus, an individual who develops looser stools than usual has diarrhoea even though the stools may be within the range of normal with respect to consistency. According to the United States Centre for Disease Control and Prevention (CDC, 2006), with diarrhoea, stools typically are looser whether or not the frequency of bowel movements is increased. This looseness of stool which can vary all the way from slightly soft to watery is caused by increased water in the stool. Increased amounts of water in stool can occur if the stomach and/or small intestine produce too much fluid, the distal small intestine and colon do not soak up enough water, or the undigested, liquid food passes too quickly through the small intestine and colon for them to take out enough water. Of course, more than one of these anomalous processes may occur at the same time. For example, some viruses, bacteria and parasites cause increased discharge of fluid, either by invading and inflaming the lining of the small intestine (inflammation stimulates the lining to secrete fluid) or by producing toxins (chemicals) that also fire up the lining to secrete fluid but without caus ing inflammation. Swelling of the small intestine and/or colon from bacteria or from ileitis/colitis can increase the haste with which food passes through the intestines, reducing the time that is available for absorbing water. Conditions of the colon such as collagenous colitis can also impede the capacity of the colon to soak up water. Escherichia coli O157:H7 is probably the most dreaded bacteria today among parents of young children. The name of the bacteria refers to the chemical compounds found on the bacteriums surface. Cattle are the main sources of E. coli O157:H7, but these bacteria also can be found in other domestic and wild mammals. E. coli O157:H7 became a household word in 1993 when it was recognized as the cause of four deaths and more than 600 cases of bloody diarrhoea among children under 5years in North-western United States (US EPA, 1996). The Northwest epidemic was traced to undercooked hamburgers served in a fast food restaurant. Other sources of outbreaks have included raw milk, unpasteurized apple juice, raw sprouts, raw spinach, and contaminated water. Most strains of E. coli bacteria are not dangerous however, this particular strain attaches itself to the intestinal wall and then releases a toxin that causes severe abdominal cramps, bloody diarrhoea and vomiting that lasts a week or longer. In small children and the elderly, the disease can advance to kidney failure. The good news is that E. coli O157:H7 is easily destroyed by cooking to 160F throughout. Reducing diarrhoea morbidity with USAIDs Framework To attain noteworthy improvement in reducing the number of deaths attributed to diarrhoea, its fundamental causes must be addressed. It is approximated that 90% of all cases of diarrhoea can be attributed to three major causes: insufficient sanitation, inadequate hygiene, and contaminated water (WHO 1997). According to USAID, for further progress to be made in the fight against diarrhoea, the concentration will need to include prevention, especially in child health programs. The first method, case management of diarrhoea, has been tremendously successful in recent years in reducing child mortality. The primary process of achieving effect has been through the initiation and operation of oral rehydration therapy; i.e. the dispensation of oral rehydration solution and sustained feeding (both solid and fluid, including breast milk). In addition, health experts have emphasized the need for caretakers to become aware of the danger signs early in children under their care and to obtain suitable, appropriate care to avoid severe dehydration and death. The second approach, increasing host resistance to diarrhoea, has also had some victory with the enhancement of a childs nutritional status and vaccination against measles, a familiar cause of diarrhoea. The third element is prevention through hygiene improvement. Although the health care system has dealt comprehensively with the symptoms of diarrhoea, it has done insufficiently to bring down the overall incidence of the disease. Despite a drop in deaths owing to diarrhoea, morbidity or the health burden due to diarrhoea has not decreased, because health experts are treating the symptoms but not addressing the causes. Thus, diarrhoeas drain on the health system, its effects on household finances and education, and its additional burden on mothers has not been mitigated . Programs in several countries have confirmed that interventions can and do reduce diarrhoea morbidity. A critical constituent of successful prevention efforts is an effective monitoring and appraisal strategy. In order to reduce transmission of faecal-oral diseases at the household level, for example, an expert group of epidemiologist and water supply and sanitation specialist concluded that three interventions would be crucial. These are: Safer disposal of human excreta, particularly of babies and people with diarrhoea. Hand washing after defecation and handling babies faeces and before feeding, eating and preparing food, and; Maintaining drinking water free from faecal contamination in the home and at the source (WHO, 1993). Studies on hand washing, as reported in Boot and Cairncross (1993), confirm that it is not only the act of hand washing, but also how well hands are washed that make a difference. To prevent diarrhoea, its causes must first be fully tacit. According to the USAIDs hygiene improvement framework, a thorough approach to diarrhoea at the national level must tackle the three key elements of any triumphant program to fight disease. These are; contact with the necessary hardware or technologies, encouragement of healthy behaviours, and assistance for long-term sustainability. The concept is explained by figure 3.3 below; The first part, water supply systems, addresses mutually the issue of water quality and water quantity, which reduces the risk of contamination of food and drink. Similarly, ensuring access to water supply systems can greatly ease the time women spend collecting water, allowing more time to care for young children and more time for income generating activities. The third element, household technologies and materials, refers to the increased accessibility to such hygiene supplies as soap (or local substitutes), chlorine, filters, water storage containers that have restricted necks and are covered, and potties for small children. The second element of the hardware component, toilet facilities, involves providing facilities to dispose off human excreta in ways that safeguard the environment and public health, characteristically in the form of numerous kinds of latrines, septic tanks, and water-borne toilets. Sanitation reporting is important because faecal contamination can spread from one household to another, especially in closely populated areas. WATER QUALITY STANDARDS AND GUIDELINES Water quality is defined in terms of the chemical, physical, and biological constituents in water. The word standards is used to refer to legally enforceable threshold values for the water parameters analyzed, while guidelines refer to threshold values that are recommended and do not have any regulatory status. This study employs the world health organization (WHO) and the Ghana standards board (GSB) standards and guidelines in determining the quality of water. Water Quality Requirements for Drinking Water – Ghana Standards The Ghana Standards for drinking water (GS 175-Part 1:1998) indicate the required physical, chemical, microbial and radiological properties of drinking water. The standards are adapted from the World Health Organizations Guidelines for Drinking Water Quality, Second Edition, Volume 1, 1993, but also incorporate national standards that are specific to the countrys environment. Physical Requirements The Ghana Standards set the maximum turbidity of drinking water at 5 NTU. Other physical requirements pertain to temperature, odour, taste and colour. Temperature, odour and taste are generally not to be objectionable, while the maximum threshold values for colour are given quantitatively as True Colour Units (TCU) or Hazen units. The Ghana Standards specify 5 TCU or 5 Hazen units for colour after filtration. The requirements for pH values set by the Ghana Standards for drinking water is 6.5 to 8.5 (GS 175-Part1:1998). Microbial Requirements The Ghana Standards specify that E.coli or thermotolerant bacteria and total coliform bacteria should not be detected in a 100ml sample of drinking water (0 CFU/100ml). The Ghana Standards also specify that drinking water should be free of human enteroviruses. WHO Drinking Water Guidelines Physical Requirements Although no health-based guideline is given by WHO (2006) for turbidity in drinking water, it is recommended that the median turbidity should ideally be below 0.1 NTU for effective disinfection. Microbial Requirements Like the Ghana Standards, no E.coli or thermotolerant bacteria should be detected in a 100 ml sample of drinking water. Water Related Diseases Every year, water-related diseases claim the lives of 3.4 million people, the greater part of whom are children (Dufour et. al, 2003). Water-related diseases can be grouped into four categories ( Bradley, 1977) based on the path of transmission: waterborne diseases, water-washed diseases, water-based diseases, insect vector-related diseases. Waterborne diseases are caused by the ingestion of water contaminated by human or animal faeces or urine containing pathogenic bacteria or viruses. These include cholera, typhoid, amoebic and bacillary dysentery and other diarrhoeal diseases. Water washed diseases are caused by poor personal hygiene and skin or eye contact with contaminated water. These include scabies, trachoma and flea, lice and tick-borne diseases. Water-based diseases are caused by parasites found in intermediate organisms living in contaminated water. These include dracunculiasis, schistosomiasis and other helminths. Water related diseases are caused by insect vectors, especially mosquitoes that breed in water. They include dengue, filariasis, malaria, onchocerciasis, trypanosomiasis and yellow fever. The Theory of Social Learning Learning is any relatively permanent change in behaviour that can be attributed to experience (Coon, 1989). According to the social learning theory, behavioural processes are directly acquired by the continually dynamic interplay between the individual and its social environment (Mc Connell, 1982). For example, children learn what to do at home by observing what happens when their siblings talk back to their parents or throw rubbish into the household compound. The learning process occurs through reinforcement and punishment. Reinforcement refers to any event that increases chances that a response will occur again (Coon, 1989). Reinforcement and punishment can be learned through education where the person can read about what happens to people as a result of actions they make. The elementary unit of society is the household and this can be defined as a residential group of persons who live under the same roof and eat out of the same pot (Friedman, 1992). Social learning is necessary for the household in acquiring the skills pertinent to the maintenance of health promoting behaviour. Most of our daily activities are learned in the household. Individuals begin to learn behaviour patterns from childhood by observing especially the parents and later on their siblings. The environment is understood as comprising the whole set of natural or biophysical and man-made or socio-cultural systems, in which man and other organisms live, work or interact (Ocran, 1999). The environment is human lifes supporting system from which food, air and shelter are derived to sustain human life. Humans interact with the physical and man-made environment and this interaction creates a complex, finely balanced set of structures and processes, which evolve over the history of a people. These structures and processes determine the culture of the society, their social behaviour, beliefs and superstition about health and diseases. Social relationships seem to protect individuals against behavioural disorders and they facilitate health promoting behaviour (Barlow and Durand, 1995; Ho Factors Influencing Sanitation Conditions Factors Influencing Sanitation Conditions ABSTRACT This thesis examines the socio-cultural and demographic factors influencing sanitation conditions, identifies the presence of Escherichia coli in household drinking water samples and investigates prevalence of diarrhoea among infants. It is based on questionnaire interviews of 120 household heads and 77 caretakers of young children below the age of 5years, direct observation of clues of household sanitation practice as well as analyses of household water samples in six surrounding communities in Bogoso. Data collected was analysed using SPSS and the Pearson Product Moment Correlation Value(R) technique. The findings revealed that the sanitation condition of households improved with high educational attainment and ageing household heads. On the contrary, sanitation deteriorated with overcrowding in the household. Furthermore, in houses where the religion of the head of household was Traditional, sanitation was superior to those of a Christian head and this household also had better sa nitary conditions than that with a Moslem head of household. Water quality analysis, indicated that 27 samples out of the 30 representing 90% tested negative for E. Coli bacteria whilst 17(56.7%) samples had acceptable levels of total Escherichia coli. Finally, it was found out that diarrhoea among infants were highly prevalent since 47 (61.04%) out of the 77 child minders admitted their wards had a bout with infant diarrhoea. Massive infrastructural development, supported by behavioural change education focussing on proper usage of sanitary facilities is urgently needed in these communities to reduce the incidence of public health diseases. Intensive health education could also prove vital and such programs must target young heads of household, households with large family size and households whose heads are Christians and Moslems. CHAPTER ONE INTRODUCTION BACKGROUND TO THE STUDY Efforts to assuage poverty cannot be complete if access to good water and sanitation systems are not part. In 2000, 189 nations adopted the United Nations Millennium Declaration, and from that, the Millennium Development Goals were made. Goal 4, which aims at reducing child mortality by two thirds for children under five, is the focus of this study. Clean water and sanitation considerably lessen water- linked diseases which kill thousands of children every day (United Nations, 2006). According to the World Health Organization (2004), 1.1 billion people lacked access to an enhanced water supply in 2002, and 2.3 billion people got poorly from diseases caused by unhygienic water. Each year 1.8 million people pass away from diarrhoea diseases, and 90% of these deaths are of children under five years (WHO, 2004). Ghana Water and Sewerage Corporation (GWSC) had traditionally been the major stakeholder in the provision of safe water and sanitation facilities. Since the 1960s the GWSC has focussed chiefly on urban areas at the peril of rural areas and thus, rural communities in the Wassa West District are no exception. According to the Ghana 2003 Core Welfare Indicators Questionnaire (CWIQ II) Survey Report (GSS, 2005), roughly 78% of all households in the Tamale Metropolis, 97 percent in Accra, 86% in Kumasi and 94% in Sekondi-Takoradi own pipe-borne water. Once more, the report show that a few households do not own any toilet facilities and depend on the bush for their toilet needs, that is 2.1%, 7.3%, and 5% for Accra, Kumasi, and Sekondi-Takoradi correspondingly. Access to safe sanitation, improved water and improved waste disposal systems is more of an urban than rural occurrence. In the rural poor households, only 9.2% have safe sanitation, 21.1% use improved waste disposal method and 63.0 % have access to improved water. The major diseases prevalent in Ghana are malaria, yellow fever, schistosomiasis (bilharzias), typhoid and diarrhea. Diarrhea is of precise concern since it has been recognized as the second most universal disease treated at clinics and one of the major contributors to infant mortality (UNICEF, 2004). The infant mortality rate currently stands at about 55 deaths per 1,000 live births (CIA, 2006). The Wassa West District of Ghana has seen an improvement in water and sanitation facilities during the last decade. Most of the development projects in the district are sponsored by the mining companies, individuals and some non-governmental organisations (NGOs). Between 2002 and 2008, Goldfields Tarkwa Mine constructed 118 new hand dug wells (77 of which were fitted with hand pumps) and refurbished 48 wells in poor condition. Also, a total of 44 modern style public water closets, were constructed in their catchment areas. The company also donated 19 large refuse collection containers to the District Assembly and built 6 new nurses quarters. The Tarkwa Mine has so far spent 10.5million US dollars of which 26% went into health, water and sanitation projects, 24% into agricultural development, 31% into formal education and the remaining went into other projects like roads and community centre construction ( GGL, 2008). Golden Star Resources (consist of Bogoso/Prestea Mine and Wassa Min e at Damang) also established the community development department in 2005 and has since invested 800 thousand US dollars. Their projects include 22 Acqua-Privy toilets, 10 hand dug wells (all fitted with hand pumps) and supplied potable water to villages with their tanker trucks (BGL, 2007). Other development partners complimenting the efforts of the central government include NGOs WACAM, Care International and Friends of the Nation (FON). WACAM is an environmentally based NGO which monitors water pollution by large scale mining companies. They have sponsored about 10 hand dug wells for villages in the district. Care International sponsors hygiene and reproductive health programmes in schools and on radio. They have also donated a couple of motor bicycles to public health workers in the district who travel to villages. The aims of all these projects were to improve hygiene and sanitation so as to reduce disease transmission. Despite efforts by the development partners, water supply and sanitation related diseases are highly prevalent in the district. Data obtained from the Public and Environmental Health Department of the Ministry of Health (M.O.H., 2008) showed that the top ten most prevalent diseases in the district include malaria, acute respiratory infections, skin diseases and diarrhoea. The others are acute eye infection, rheumatism, dental carries, hypertension, pregnancy related complications and home/occupational accidents. A lot more illnesses occur but on a lower scale and these include intestinal worms, coughs and typhoid fever. A complete data on the top ten diseases prevalent in the district is attached as Appendix D but below is a selection of the illnesses that directly result from bad water and sanitation practices. The number of malaria cases decreased from 350 in 2006 to 300 cases per 1000 population in 2008. Despite the decrease, the values involved are still quite high. The incidence of diarrhoea among infants and acute respiratory infection remained 30 and 60 cases per 1,000 populations respectively. This can be attributed to several reasons, including population boom, lack of uninterrupted services and inadequate functioning facilities. In fact, according to the World Health Organization (WHO, 2004), an estimated 90% of all incidence of diarrhoea among infants can be blamed on inadequate sanitation and unclean water. For example, in a study of 11 countries in Sub-Saharan Africa, only between 35-80% of water systems were operational in the rural areas (Sutton, 2004). Another survey in South Africa recognized that over 70% of the boreholes in the Eastern Cape were not working (Mackintosh and Colvin, 2003). Further examples of sanitation systems in bad condition have also been acknowledged in rural Ghana, where nearly 40% of latrines put up due to the support of a sanitation program were uncompleted or not used (Rodgers et al., 2007). The author had a personal communication with the District Environmental Officer and he estimated that, approximately there are 224 public toilets, 560 hand dug wells, 1,255 public standpipes and 3 well managed waste disposal sites in the district. According to the 2006 projection, the population of the district is expected to reach 295,753 by the end of the year 2009 (WWDA, 2006). Development partners in the past have concentrated their efforts on facilities provision only. They have not looked well at the possible causes of the persistence of disease transmission despite the effort they are making. Relationships between households socio cultural demographic factors and peoples behaviour with respect to the practice of hygiene could prove an essential lead to the solution of the problem. The fact is, merely providing a water closet does not guarantee that it could be adopted by the people and used well to reduce disease transmission. Epidemiological investigations have revealed that even in dearth supply of latrines, diarrhoeal morbidity can be reduced with the implementation of improved hygiene behaviours (IRC, 2001: Morgan, 1990). Access to waste disposal systems, their regular, consistent and hygienic use and adoption of other hygienic behavioural practices that block the transmission of diseases are the most important factors. In quite a lot of studies fro m different countries, the advancement of personal and domestic hygiene accounted for a decline in diarrhoeal morbidity (Henry and Rahim, 1990). The World Bank, (2003) identifies the demographic characteristics of the household including education of members, occupation, size and composition as influencing the willingness of the household to use an improved water supply and sanitation system. Education, especially for females results in well spaced child birth, greater ability of parents to give better health care which in turn contribute to reduced mortality rates among children under 5years (Grant, 1995). In a study into water resource scarcity in coastal Ghana, Hunter (2004) identified a valid association between household size, the presence of young children and the gender of the household head. It was noted that, female heads were less likely to collect water in larger households. Furthermore, increasing number of young children present increased the odds of female head/spouse being the household water collector. Cultural issues play active part in hygiene and sanitation behaviour especially among members of rural communities. For example, women are hardly seen urinating in public due to a perceived shame in the act but men can be left alone if found doing it. Also, the act of defecation publicly is generally unacceptable except when infants and young children are involved. The reason is that the faeces from young people are allegedly free from pathogens and less offensive (Drangert, 2004). Ismails (1999) work on nutritional assessment in Africa, detected that peoples demographic features, socioeconomic and access to basic social services such as food, water and electricity correlate significantly to their health and nutrition status. Specifically, factors such as age, gender, township status and ethnicity, which are basic to demography, can play a role in the quality of life especially of the elderly. This research assessed peoples practice of personal hygiene in Bogoso and surrounding villages. It also identified the common bacteria present in household stored water sources. Furthermore, the research identified the relationships between some socio-cultural demographic factors of households and the sanitation practice of its members. THE PROBLEM STATEMENT The Wassa West District in the Western Region is home to six large scale mining companies and hundreds of small scale and illegal mining units. Towns and villages in the district have been affected by mining, forestry and agricultural activities for over 120 years (BGL EIS, 2005). Because of this development, the local environment has been subjected to varying degrees of degradation. For example, water quality analysis carried out in 1989 by the former Canadian Bogoso Resources (CBR) showed that water samples had Total coliform bacteria in excess of 16 colonies per 100ml (BGL EIS,2005). Most of the water and sanitation programs executed in the district exerted little positive impact and thus, diarrhoeal diseases are still very high in the towns and villages (See Appendix D on page 80). However, in order to solve any problem it is important to appreciate the issues that contribute to it; after all, identifying the problem in itself is said to be a solution in disguise. Numerous health impact research have evidently recognized that the upgrading of water supply and sanitation alone is generally required but not adequate to attain broad health effects if personal and domestic hygiene are not given equivalent prominence (Scherlenlieb, 2003). The troubles of scarce water and safe sanitation provisions in developing countries have previously been dealt with by researchers for quite some time. However, until recent times they were mostly considered as technical and/or economic problems. Even rural water and sanitation issues are repeatedly dealt with from an entirely engineering point of view, with only a simple reference to social or demographic aspects. Therefore, relatively not much is proven how the socio-cultural demographic influences impinge on hygiene behaviour which in turn influences the transmission of diseases. The relationship between household socio cultural factors and the sanitation conditions of households in the Wassa West District especially the Bogoso Rural Council area has not been systematically documented or there is inadequate research that investigates such relationship. THE RESEARCH QUESTIONS The following research questions were posed to help address the objectives; Why are the several sanitation intervention projects failing to achieve desired results? Why is the prevalence of malaria and diarrhea diseases so high in the district? What types of common bacteria are prevalent in the stored drinking water of households? OBJECTIVES The main aim of this research was to investigate peoples awareness and practice of personal hygiene, access to quality water and sanitation and the possible causes of diarrhoeal diseases and suggest ways to reduce the incidence of diseases in the community. The specific objectives were; To assess the quality of stored household drinking water To establish the extent to which sanitation behaviour is affected by household socio-cultural demographic factors like age and education level of the head. To investigate the occurrence of diarrhoea among young children (0-59 months old) in the households. To identify and recommend good intervention methods to eliminate or reduce the outbreak of diseases and improve sanitation. HYPOTHESIS In addition to the above objectives, the following hypotheses were tested; Occurrence of infant diarrhoea in the household is independent on the educational attainment of child caretakers. There is no relationship between households background factors and the sanitation conditions of the household. CHAPTER TWO LITERATURE REVIEW In this chapter, various literature related to the subject matter of study are reviewed. Areas covered are sanitation, hygiene, water quality and diarrhoeal diseases. Theories and models the study contributed to include USAIDs Sanitation Improvement Framework, the F diagram by Wagner and Lanois and the theory of Social learning. SANITATION Until recently, policies of many countries have focused on access to latrines by households as a principal indicator of sanitation coverage, although of late there has been a change and an expansion in understanding the term sanitation. Sanitation can best be defined as the way of collecting and disposing of excreta and community liquid waste in a germ-free way so as not to risk the health of persons or the community as a whole (WEDC, 1998). Ideally, sanitation should end in the seclusion or destruction of pathogenic material and, hence, a breach in the transmission pathway. The transmission pathways are well known and are potted and simplified in the F diagram (Wagner and Lanois 1958) shown below by figure 3.1. The more paths that can be blocked, the more useful a health and sanitation intervention program will be. It may be mentioned that the health impact indicators of sanitation programmes are not easy to define and measure, particularly in the short run. Therefore, it seems more reasonable to look at sanitation as a package of services and actions which taken together can have some bearing on the health of a person and health status in a community. According to IRC (2001:0), issues that need to be addressed when assessing sanitation would include: How complete the sanitation programme is in addressing major risks for transmitting sanitation-related diseases; Whether the sanitation programme adopted a demand driven approach, through greater peoples participation, or supply driven approach, through heavy subsidy; Whether it allows adjustment to peoples varying needs and payment; If the programme leads to measurably improved practices by the majority of men and women, boys and girls; If it is environmentally friendly. That is; if it does not increase or create new environmental hazards (IRC, 2001) Sanitation is a key determinant of both fairness in society and societys ability to maintain itself. If the sanitation challenges described above cannot be met, we will not be able to provide for the needs of the present generation without hindering that of future generations. Thus, sanitation approaches must be resource minded, not waste minded. HYGIENE Hygiene is the discipline of health and its safeguarding (Dorland, 1997). Health is the capacity to function efficiently within ones surroundings. Our health as individuals depends on the healthfulness of our environment. A healthful environment, devoid of risky substances allows the individual to attain complete physical, emotional and social potential. Hygiene is articulated in the efforts of an individual to safeguard, sustain and enhance health status (Anderson and Langton, 1961). Measures of hygiene are vital in the fight against diarrhoeal diseases, the major fatal disease of the young in developing countries (Hamburg, 1987). The most successful interventions against diarrhoeal diseases are those that break off the transmission of contagious agents at home. Personal and domestic hygiene can be enhanced with such trouble-free actions like ordinary use of water in adequate quantity for hand washing, bathing, laundering and cleaning of cooking and eating utensils; regular washing and change of clothes; eating healthy and clean foods and appropriate disposal of solid and liquid waste. Diarrheal Dise ases Diarrhoea can be defined in absolute or relative terms based on either the rate of recurrence of bowel movements or the constancy (or looseness) of stools (Kendall, 1996). Absolute diarrhoea is having more bowel movements than normal. Relative diarrhoea is defined based on the consistency of stool. Thus, an individual who develops looser stools than usual has diarrhoea even though the stools may be within the range of normal with respect to consistency. According to the United States Centre for Disease Control and Prevention (CDC, 2006), with diarrhoea, stools typically are looser whether or not the frequency of bowel movements is increased. This looseness of stool which can vary all the way from slightly soft to watery is caused by increased water in the stool. Increased amounts of water in stool can occur if the stomach and/or small intestine produce too much fluid, the distal small intestine and colon do not soak up enough water, or the undigested, liquid food passes too quickly through the small intestine and colon for them to take out enough water. Of course, more than one of these anomalous processes may occur at the same time. For example, some viruses, bacteria and parasites cause increased discharge of fluid, either by invading and inflaming the lining of the small intestine (inflammation stimulates the lining to secrete fluid) or by producing toxins (chemicals) that also fire up the lining to secrete fluid but without caus ing inflammation. Swelling of the small intestine and/or colon from bacteria or from ileitis/colitis can increase the haste with which food passes through the intestines, reducing the time that is available for absorbing water. Conditions of the colon such as collagenous colitis can also impede the capacity of the colon to soak up water. Escherichia coli O157:H7 is probably the most dreaded bacteria today among parents of young children. The name of the bacteria refers to the chemical compounds found on the bacteriums surface. Cattle are the main sources of E. coli O157:H7, but these bacteria also can be found in other domestic and wild mammals. E. coli O157:H7 became a household word in 1993 when it was recognized as the cause of four deaths and more than 600 cases of bloody diarrhoea among children under 5years in North-western United States (US EPA, 1996). The Northwest epidemic was traced to undercooked hamburgers served in a fast food restaurant. Other sources of outbreaks have included raw milk, unpasteurized apple juice, raw sprouts, raw spinach, and contaminated water. Most strains of E. coli bacteria are not dangerous however, this particular strain attaches itself to the intestinal wall and then releases a toxin that causes severe abdominal cramps, bloody diarrhoea and vomiting that lasts a week or longer. In small children and the elderly, the disease can advance to kidney failure. The good news is that E. coli O157:H7 is easily destroyed by cooking to 160F throughout. Reducing diarrhoea morbidity with USAIDs Framework To attain noteworthy improvement in reducing the number of deaths attributed to diarrhoea, its fundamental causes must be addressed. It is approximated that 90% of all cases of diarrhoea can be attributed to three major causes: insufficient sanitation, inadequate hygiene, and contaminated water (WHO 1997). According to USAID, for further progress to be made in the fight against diarrhoea, the concentration will need to include prevention, especially in child health programs. The first method, case management of diarrhoea, has been tremendously successful in recent years in reducing child mortality. The primary process of achieving effect has been through the initiation and operation of oral rehydration therapy; i.e. the dispensation of oral rehydration solution and sustained feeding (both solid and fluid, including breast milk). In addition, health experts have emphasized the need for caretakers to become aware of the danger signs early in children under their care and to obtain suitable, appropriate care to avoid severe dehydration and death. The second approach, increasing host resistance to diarrhoea, has also had some victory with the enhancement of a childs nutritional status and vaccination against measles, a familiar cause of diarrhoea. The third element is prevention through hygiene improvement. Although the health care system has dealt comprehensively with the symptoms of diarrhoea, it has done insufficiently to bring down the overall incidence of the disease. Despite a drop in deaths owing to diarrhoea, morbidity or the health burden due to diarrhoea has not decreased, because health experts are treating the symptoms but not addressing the causes. Thus, diarrhoeas drain on the health system, its effects on household finances and education, and its additional burden on mothers has not been mitigated . Programs in several countries have confirmed that interventions can and do reduce diarrhoea morbidity. A critical constituent of successful prevention efforts is an effective monitoring and appraisal strategy. In order to reduce transmission of faecal-oral diseases at the household level, for example, an expert group of epidemiologist and water supply and sanitation specialist concluded that three interventions would be crucial. These are: Safer disposal of human excreta, particularly of babies and people with diarrhoea. Hand washing after defecation and handling babies faeces and before feeding, eating and preparing food, and; Maintaining drinking water free from faecal contamination in the home and at the source (WHO, 1993). Studies on hand washing, as reported in Boot and Cairncross (1993), confirm that it is not only the act of hand washing, but also how well hands are washed that make a difference. To prevent diarrhoea, its causes must first be fully tacit. According to the USAIDs hygiene improvement framework, a thorough approach to diarrhoea at the national level must tackle the three key elements of any triumphant program to fight disease. These are; contact with the necessary hardware or technologies, encouragement of healthy behaviours, and assistance for long-term sustainability. The concept is explained by figure 3.3 below; The first part, water supply systems, addresses mutually the issue of water quality and water quantity, which reduces the risk of contamination of food and drink. Similarly, ensuring access to water supply systems can greatly ease the time women spend collecting water, allowing more time to care for young children and more time for income generating activities. The third element, household technologies and materials, refers to the increased accessibility to such hygiene supplies as soap (or local substitutes), chlorine, filters, water storage containers that have restricted necks and are covered, and potties for small children. The second element of the hardware component, toilet facilities, involves providing facilities to dispose off human excreta in ways that safeguard the environment and public health, characteristically in the form of numerous kinds of latrines, septic tanks, and water-borne toilets. Sanitation reporting is important because faecal contamination can spread from one household to another, especially in closely populated areas. WATER QUALITY STANDARDS AND GUIDELINES Water quality is defined in terms of the chemical, physical, and biological constituents in water. The word standards is used to refer to legally enforceable threshold values for the water parameters analyzed, while guidelines refer to threshold values that are recommended and do not have any regulatory status. This study employs the world health organization (WHO) and the Ghana standards board (GSB) standards and guidelines in determining the quality of water. Water Quality Requirements for Drinking Water – Ghana Standards The Ghana Standards for drinking water (GS 175-Part 1:1998) indicate the required physical, chemical, microbial and radiological properties of drinking water. The standards are adapted from the World Health Organizations Guidelines for Drinking Water Quality, Second Edition, Volume 1, 1993, but also incorporate national standards that are specific to the countrys environment. Physical Requirements The Ghana Standards set the maximum turbidity of drinking water at 5 NTU. Other physical requirements pertain to temperature, odour, taste and colour. Temperature, odour and taste are generally not to be objectionable, while the maximum threshold values for colour are given quantitatively as True Colour Units (TCU) or Hazen units. The Ghana Standards specify 5 TCU or 5 Hazen units for colour after filtration. The requirements for pH values set by the Ghana Standards for drinking water is 6.5 to 8.5 (GS 175-Part1:1998). Microbial Requirements The Ghana Standards specify that E.coli or thermotolerant bacteria and total coliform bacteria should not be detected in a 100ml sample of drinking water (0 CFU/100ml). The Ghana Standards also specify that drinking water should be free of human enteroviruses. WHO Drinking Water Guidelines Physical Requirements Although no health-based guideline is given by WHO (2006) for turbidity in drinking water, it is recommended that the median turbidity should ideally be below 0.1 NTU for effective disinfection. Microbial Requirements Like the Ghana Standards, no E.coli or thermotolerant bacteria should be detected in a 100 ml sample of drinking water. Water Related Diseases Every year, water-related diseases claim the lives of 3.4 million people, the greater part of whom are children (Dufour et. al, 2003). Water-related diseases can be grouped into four categories ( Bradley, 1977) based on the path of transmission: waterborne diseases, water-washed diseases, water-based diseases, insect vector-related diseases. Waterborne diseases are caused by the ingestion of water contaminated by human or animal faeces or urine containing pathogenic bacteria or viruses. These include cholera, typhoid, amoebic and bacillary dysentery and other diarrhoeal diseases. Water washed diseases are caused by poor personal hygiene and skin or eye contact with contaminated water. These include scabies, trachoma and flea, lice and tick-borne diseases. Water-based diseases are caused by parasites found in intermediate organisms living in contaminated water. These include dracunculiasis, schistosomiasis and other helminths. Water related diseases are caused by insect vectors, especially mosquitoes that breed in water. They include dengue, filariasis, malaria, onchocerciasis, trypanosomiasis and yellow fever. The Theory of Social Learning Learning is any relatively permanent change in behaviour that can be attributed to experience (Coon, 1989). According to the social learning theory, behavioural processes are directly acquired by the continually dynamic interplay between the individual and its social environment (Mc Connell, 1982). For example, children learn what to do at home by observing what happens when their siblings talk back to their parents or throw rubbish into the household compound. The learning process occurs through reinforcement and punishment. Reinforcement refers to any event that increases chances that a response will occur again (Coon, 1989). Reinforcement and punishment can be learned through education where the person can read about what happens to people as a result of actions they make. The elementary unit of society is the household and this can be defined as a residential group of persons who live under the same roof and eat out of the same pot (Friedman, 1992). Social learning is necessary for the household in acquiring the skills pertinent to the maintenance of health promoting behaviour. Most of our daily activities are learned in the household. Individuals begin to learn behaviour patterns from childhood by observing especially the parents and later on their siblings. The environment is understood as comprising the whole set of natural or biophysical and man-made or socio-cultural systems, in which man and other organisms live, work or interact (Ocran, 1999). The environment is human lifes supporting system from which food, air and shelter are derived to sustain human life. Humans interact with the physical and man-made environment and this interaction creates a complex, finely balanced set of structures and processes, which evolve over the history of a people. These structures and processes determine the culture of the society, their social behaviour, beliefs and superstition about health and diseases. Social relationships seem to protect individuals against behavioural disorders and they facilitate health promoting behaviour (Barlow and Durand, 1995; Ho

Information about current influences on planning Essay

1. Every child matter influences planning and provision of learning opportunities The National Curriculum is the starting point for planning a school curriculum that meets the specific needs of individuals and groups of pupils. This statutory inclusion statement on providing effective learning opportunities for all pupils outlines how teachers can modify, as necessary, the National Curriculum programmes of study to provide all pupils with relevant and appropriately challenging work at each key stage. Child care act 2006 influences planning and provision of learning opportunities this act states that early years providers have a duty to implement the EYFS. We do this by meeting the learning and development requirements when doing our weekly planning and we also comply with the welfare requirements. Child care act does this to ensure that it is very important to follow rules and regulations to ensure that the children are at the right stages of development in life. SEN code of practice 2002 influences planning and provision of learning opportunities areas covered include the definition of special educational needs, parental responsibility and working partnership with parents. The code also looks at: involving pupils in assessment and decision-making; provision in the Early Years; primary and secondary education; statutory assessment of children under compulsory school age; and the role of the special educational needs coordinator. (2013) Special Educational Needs: Code of Practice. The SEN code do this to ensure that disability children do not miss out on key learning development and also to make sure that they do not feel left out or intimidated. Equality act 2010 influences planning and provision of learning opportunities this act makes sure that no one gets treated differently to anybody else this helps planning and provision because it makes sure that staff have to make sure that when they plan a activity or a lesson plan it’s got to be able to involve everyone and make sure that it suits all individual needs. ‘’ Objectives must be appropriate, focusing on the most pressing equality  gaps.’’ 2. Inspectors found that where assessment was underdeveloped it tended to focus more on children’s welfare or their interests, rather than their learning. Self-evaluation and action-planning was too often seen by childcare providers as something that had to be done for Ofsted rather than a means of improving outcome for children. However, outcomes for children were no better than satisfactory in any of the providers where self-evaluation was inadequate (2011) Press release: A good start for the Early Years Foundation Stage. Ofsted make sure that it is seen to be important to plan different types of learning opportunities for the children as this helps to develop the children’s skills in a variety of way. For example ofsted inspect schools by sitting in on different subjects and different teacher’s lessons, they do this to make sure that everyone is doing it as correctly as they aspect to see. 3. The curriculum frameworks like the EYFS influence planning and provision of learning opportunities. The term curriculum is used to describe everything children do, see, hear or feel in their setting, both planned and unplanned. The Early Years Foundation Stage is the statutory framework against which providers of early education are judged, and includes requirements for the provision of young children’s learning and development, and welfare. The report focuses particularly on two areas of learning: personal, social and emotional development; and communication, language and literacy skills. 4. Learning through landscapes supports families in the early years by showing children the outdoors and learning them new activities such as gardening and discovering nature with their own opinions and physically learning by touch and seeing things from their point of view. â€Å"I believe the work of Learning through Landscapes is needed even more than ever. I hope  you will share our passion for giving children opportunities for discovery and learning that will illuminate their entire lives.† Attenborough.D (2005) Learning through Landscapes.   EPPSE (3-14) supports families in the early years by making sure those children do get assessed at the age of 3 before they go to pre-school and then the child will be monitored until they do enter school. This helps by knowing what the child abilities are being noticed and noted. ‘’ More than 3,000 children were assessed at the start of pre-school around the age of 3 and their development was monitored until they en tered school around the age of 5.’’ Leading education and social research (Updated 2013) Effective Pre-School, Primary & Secondary Education (EPPSE).   Primary and Secondary Education 3-14 (EPPSE 3-14 project) a major longitudinal study investigating the influence of pre-school, primary and secondary school on children’s cognitive and social/behavioural development in England.

Evangelou.M (2008) Effective Pre-school, Primary and Secondary Education 3-14 Project (EPPSE 3-14).   Neighbourhood nurseries support families in the early years by making sure that families can get to close nursery without struggling and panicking that they cannot reach a nursery which prevents the child even going into nursery. ‘’The Neighbourhood Nurseries Initiative (NNI) aims to expand childcare provision in the 20% most disadvantaged areas of Engla nd by creating 45,000 new day-care places for children aged nought to five.’’

The life cycle of a star

In this physics coursework, I have been asked to carry out research of my selection and to develop it. I have selected to research the life cycle of a star, and I would conduct this by gathering the necessary information in a form of a report which explains this in detail. I have chosen to explore this particular topic firstly because I am extremely fascinated in space and the universe and secondly because I do not know much about the life cycle of a star and I deem this will help extend my knowledge. Firstly when carrying out this research before describing the life cycle of a star I need to be familiar of what a star is, and how it is formed What is a star, and how does it form? Stars are basically huge balls of hydrogen gas. Hydrogen is by far the most common element in the Universe, and stars form in clusters when large clouds of hydrogen, which naturally forms a hydrogen ‘molecule' (H+H=H2) with another atom, collapse. The hydrogen clouds collapses very slowly, although they can be speeded up by the effects of a passing star, or the shockwave from a distant supernova explosion. As the cloud collapses, it speeds up its rotation, and pulls more material into the centre, where a denser ball of gas, the ‘proto-star' forms. The proto-star collapses under its own weight, and the collisions between hydrogen molecules inside it generate heat. Eventually the star becomes hot enough for the hydrogen molecules to split apart, and form atoms of hydrogen. The star keeps on collapsing under its own weight, and getting even hotter in the core, until finally it is hot enough there (roughly 10 million degrees) for it to start generating energy, by nuclear fusion – combining hydrogen atoms to form a heavier element, helium. Energy is released from the core, and pushes its way out through the rest of the star, creating an outward pressure which stops the star's collapse. When the energy emerges from the star, it is in the form of light, and the star has begun to shine. A Star is formed from a cloud of gas, mostly hydrogen, and the dust that is initially spread over a huge volume, but which is pulled together by its own collective gravity. This gravitational collapse of the cloud creates a body of large density, and the loss of gravitational potential energy in the process is very large indeed. The result is that the original particles acquire high kinetic energy, so that the collisions between them are very violent. Atoms lose their electrons. Not only has that, collisions taken place in which electrical repulsion of nuclei is no longer strong enough to keep them apart. They can become close enough together for the strong nuclear force to take effect, so that they merge. Fusion takes place, with hydrogen as the principal key material. This begins the process of conversion of mass to energy, and much of the released energy takes the form of photons which begins to stream from the new star. Every star then exists in a state of slowly evolving stability. On the one hand there is the trend for the material to continue to collapse under gravity. On the other hand there is a tendency for the violent thermal activity and the emission of radiation resulting from fusion to blow the material apart. The more bigger star in general, the greater is the gravitational pressure and so the higher rate of energy is released by fusion, therefore bigger stars use up their supply of fusing nuclei more quickly than do smaller stars, such that bigger stars have shorter lives. The enormous luminous energy of the stars comes from nuclear fusion processes in their centres. Depending upon the age and mass of a star, the energy may come from proton fusion, helium fusion, or the carbon cycle. For brief periods near the end of the luminous lifetime of stars, heavier elements up to iron may fuse, but since iron is at the peak of the binding energy curve, the fusion of elements more massive than iron would soak up energy rather than deliver it. This links to the below graph: Fusion in stars makes energy available to create radiation, consuming mass at an amazing rate. The sun, for example loses a mass of 4.5 million tonnes every second. Also, heavier nuclei are formed from smaller ones, so that the compression of a star changes. Concluding this, as the star dies the material dependant on its size is scattered in space. The Hertzsprung – Russell Diagram This simple graph shows ways in which to classify stars. Temperature is plotted on the x-axis. This is related to the colour as cooler stars are redder, hotter stars are bluer. Relative luminosity is plotted on the y-axis. Because of the very wide range of temperatures and stellar luminosities, logarithmic scales are used. The location of an individual star on such a graph lets us establish a loose system of classification. This graph aids us to find out what star has what temperature so we can easily classify it using the relative luminosity and temperature. Here is a diagram of the graph which shows the stars in their classified points showing their rough temperature and luminosity. So how do the changes in the stars take place? Very massive stars experience several stages in their cores. o First hydrogen fuses into helium then helium to carbon creating larger nuclei. Such large stars in later life can have shells or layers with heavier nuclei towards their centres. It is not only the life expectancy of a star that depends on its mass, but also the way which it dies. o Older stars have outer layers in which hydrogen is the fuel for fusion, while the inner layers helium is the fuel, and for massive stars there may be further layers beneath. Most stars, including the sun become red giants after the end of their equilibrium phase. o This process is started by cooling in the inner core, resulting in reduced thermal pressure and radiation pressure and so causing gravitational collapse of the hydrogen shell. But the gravitational collapse provides energy for heating the shell, and so the rate of fusion in the shell increases. This makes the shell expand enormously. o The outermost surface of the star becomes cooler, and its light becomes redder, but the larger surface area means that the stars luminosity increases. o Meanwhile the gravitational collapse affects the core as well, and ultimately the process of fusion of helium in the core cause the outer shell to expand further and thin leaving the hot extremely dense core as a white dwarf. o Slowly this cools and becomes a black dwarf. o For the stars that are several times bigger then the sun, death may be even more dramatic. A core of carbon is created by fusion of helium, and once this core is sufficiently compressed then fusion of the carbon itself takes place. The rapid release of energy makes the star briefly as bright as a galaxy, as bright as 10 billion stars. o The star explodes into a supernova and its material spreads back into the space around. In even larger stars, fusion of carbon can continue more steadily, producing still larger nuclides and ultimately creating iron nuclei. The iron nuclei also experience fusion, but these are different as they are energy consuming meaning they keep it in. The central core of the star collapses under gravity. This increases temperature but cannot now greatly increase the rate of fusion, so collapse continues. Outer layers also collapse around the core, compressing it further. It becomes denser then an atomic nucleus, protons and electrons join together to create neutrons. o Meanwhile, the collapse of the outer layers heats these, increasing the rate of fusion so that suddenly the star explodes as a supernova. This spreads the material of these layers into space, leaving a small hot body behind a neutron star. o Furthermore if this supernova is big enough, its gravity continues to pull the matter towards a single point with a huge gravitational field where not even light can escape from is known as the black hole. Star pictures obtained from Internet http://www.enchantedlearning.com/subjects/astronomy Here is an illustration of a star life cycle followed by the theory How long a star lives for and how it dies†¦ How long a star lives and how it dies, depends entirely on how massive it is when it begins. A small star can sustain basic nuclear fusion for billions of years. Our sun, for example, probably can sustain reactions for some 10 billion years. Really big stars have to conduct nuclear fusion at an enormous rate to keep in hydrostatic equilibrium and quickly falter, sometimes as fast as 40,000 years. If the star is about the same mass as the Sun, it will turn into a white dwarf star. If it is somewhat more massive, it may undergo a supernova explosion and leave behind a neutron star. But if the collapsing core of the star is very great at least three times the mass of the Sun nothing can stop the collapse. The star implodes to form an infinite gravitational warp in space, a hole. This is exemplified in a very simple diagram highlighting the consequence of each mass of the stars and what they will revolve into. Normal stars such as the Sun are hot balls of gas millions of kilometres in diameter. The visible surfaces of stars are called the photospheres, and have temperatures ranging from a few thousand to a few tens of thousand degrees Celsius. The outermost layer of a star's atmosphere is called the â€Å"corona†, which means â€Å"crown†. The gas in the coronas of stars has been heated to temperatures of millions of degrees Celsius. Most radiation emitted by stellar coronas is in X-rays because of its high temperature. Studies of X-ray emission from the Sun and other stars are therefore primarily studies of the coronas of these stars. Although the X-radiation from the coronas accounts for only a fraction of a percent of the total energy radiated by the stars, stellar coronas provide us with a cosmic laboratory for finding out how hot gases are produced in nature and how magnetic fields interact with hot gases to produce flares, spectacular explosions that release as much energy as a million hydrogen bombs The Orion Trapezium as observed. The colours represent energy; where blue and white indicate very high energies and therefore extreme temperatures. The size of the X-ray source in the image also reflects its brightness, i.e. more bright sources appear larger in size. The Life Cycle of a star: In Large Stars In hot massive stars, the energy flowing out from the centre of the star is so intense that the outer layers are literally being blown away. Unlike a nova, these stars do not shed their outer layers explosively, but in a strong, steady stellar wind. Shock waves in this wind produce X-rays; from the intensity and distribution with energy of these X-rays, astronomers can estimate the temperature, velocity and density of this wind. Medium sized Stars In medium-sized stars, such as the Sun, the outer layers consist of a rolling, boiling disorder called convection. A familiar example of convection is a sea-breeze. The Sun warms the land more quickly than the water and the warm air rises and cools as it expands. It then sinks and pushes the cool air off the ocean inland to replace the air that has risen, producing a sea-breeze. In the same way, hot gas rises from the central regions of the Sun, cools at the surface and descends again. From Red Giant To supernova Once stars that are 5 times or more massive than our Sun reach the red giant phase, their core temperature increases as carbon atoms are formed from the fusion of helium atoms. Gravity continues to pull carbon atoms together as the temperature increases and additional fusion processes proceed, forming oxygen, nitrogen, and eventually iron. As the shock encounters material in the star's outer layers, the material is heated, fusing to form new elements and radioactive isotopes. While many of the more common elements are made through nuclear fusion in the cores of stars, it takes the unstable conditions of the supernova explosion to form many of the heavier elements. The shock wave propels this material out into space. The material that is exploded away from the star is now known as a supernova remnant. The White Dwarf A star experiences an energy crisis and its core collapses when the star's basic, non-renewable energy source, hydrogen which is used up. A shell of hydrogen on the edge of the collapsed core will be compressed and heated. The nuclear fusion of the hydrogen in the shell will produce a new surge of power that will cause the outer layers of the star to expand until it has a diameter a hundred times its present value. This is called the ‘red giant' phase of a star's existence. There are other possible conditions that allow astronomers to observe X-rays from a white dwarf. These opportunities occur when a white dwarf is capturing matter from a nearby companion star. As captured matter falls onto the surface of the white dwarf, it accelerates and gains energy. This energy goes into heating gas on or just above the surface of the white dwarf to temperatures of several million degrees. The hot gas glows brightly in X-rays. A careful analysis of this process can reveal the mass of the white dwarf, its rate of rotation and the rate at which matter is falling onto it. In some cases, the matter that gathers on the surface can become so hot and dense that nuclear reactions occur. When that happens, the white dwarf suddenly becomes 10,000 times brighter as the explosive outer layers are blown away in what is called a nova outburst. After a month or so, the excitement is over and the cycle begins anew. The Supernova Every 50 years or so, a massive star in our galaxy blows itself apart in a supernova explosion. Supernovas are one of the most violent events in the universe, and the force of the explosion generates a blinding flash of radiation, as well as shock waves analogous to sonic booms. There are two types of supernovas: o Type II, where a massive star explodes o Type I, where a white dwarf collapses because it has pulled too much material from a nearby companion star onto itself. The general picture for a Type II supernova is when the nuclear power source at the centre or core of a star is exhausted, the core collapses. In less than a second, a neutron star (or black hole, if the star is extremely massive) is formed. When matter crashes down on the neutron star, temperatures rise to billions of degrees Celsius. Within hours, a disastrous explosion occurs, and all but the central neutron star is blown away at speeds in excess of 50 million kilometres per hour. A thermonuclear shock wave races through the now expanding stellar debris, fusing lighter elements into heavier ones and producing a brilliant visual outburst that can be as intense as the light of ten billion Suns. The matter thrown off by the explosion flows through the surrounding gas producing shock waves that create a shell of multimillion degrees gas and high energy particles called a supernova remnant. The supernova remnant will produce intense radio and X-radiation for thousands of years. In several young supernova remnants the rapidly rotating neutron star at the centre of the explosion gives off pulsed radiation at X-ray and other wavelengths, and creates a magnetized bubble of high-energy particles whose radiation can dominate the appearance of the remnant for a thousand years or more. Eventually, after rumbling across several thousand light years, the supernova remnant will disperse. The Neutron Stars The nucleus contains more than 99.9 percent of the mass of an atom, yet it has a diameter of only 1/100,000 that of the electron cloud. The electrons themselves take up little space, but the pattern of their orbit defines the size of the atom, which is therefore 99.9% open space. What we perceive as solid when we bump against a rock is really a disorder of electrons moving through empty space so fast that we can't see or feel the emptiness. Such extreme forces occur in nature when the central part of a massive star collapses to form a neutron star. The atoms are crushed completely, and the electrons are jammed inside the protons to form a star composed almost entirely of neutrons. The result is a tiny star that is like a gigantic nucleus and has no empty space. Neutron stars are strange and fascinating objects. They represent an extreme state of matter that physicists are eager to know more about. The intense gravitational field would pull your spacecraft to pieces before it reached the surface. The magnetic fields around neutron stars are also extremely strong. Magnetic forces squeeze the atoms into the shape of cigars. Even if a spacecraft carefully stayed a few thousand miles above the surface neutron star so as to avoid the problems of intense gravitational and magnetic fields, you would still face another potentially fatal hazard. If the neutron star is rotating rapidly, as most young neutron stars are, the strong magnetic fields combined with rapid rotation create an amazing generator that can produce electric potential differences of trillions of volts. Such voltages, which are 30 million times greater than those of lightning bolts, create deadly blizzards of high-energy particles. If a neutron star is in a close orbit around a normal companion star, it can capture matter flowing away from that star. This captured matter will form a disk around the neutron star from which it will spiral down and fall, or accrete, onto the neutron star. The in falling matter will gain an enormous amount of energy as it accelerates. Much of this energy will be radiated away at X-ray energies. The magnetic field of the neutron star can funnel the matter toward the magnetic poles, so that the energy release is concentrated in a column, or spot of hot matter. As the neutron star rotates, the hot region moves into and out of view and produces X-ray pulses. Black Holes When a star runs out of nuclear fuel, it will collapse. If the core, or central region, of the star has a mass that is greater than three Suns, no known nuclear forces can prevent the core from forming a deep gravitational damage in space called a black hole. A black hole does not have a surface in the usual sense of the word. There is simply a region, or boundary, in space around a black hole beyond which we cannot see. This boundary is called the event horizon. Anything that passes beyond the event horizon is doomed to be crushed as it descends ever deeper into the gravitational well of the black hole. No visible light, nor X-rays, nor any other form of electromagnetic radiation, or any particle, no matter how energetic, can escape. The radius of the event horizon (proportional to the mass) is very small, only 30 kilometres for a non-spinning black hole with the mass of 10 Suns.

Comparison Of Two Psychological Perspectives, Cognitive...

This essay will attempt to make a analytical comparison between two psychological perspectives, cognitive and behaviourism on what they believe about their approach to learning and also explain what the theories of two psychologist that are associated with both perspectives, highlighting the similarities and differences. AC 1.1, 1.2, Behaviourists believe that learning is a change in behaviour, when the learner is born the mind is tabula rasa (a clean slate) and behaviour is shaped by positive or negative reinforcement, learning is controlled by the teacher who supplies stimulus and reinforcement, so from a behaviourist perspective behaviour can only be learned and each action has to be learned in isolation. Cognitive theorist believe that learning is the ability to process information so they can cope with their surrounding environment, they also believe that there is an internal need to make sense of conflicting observation and that learning is a change in thinking or stored knowledge. Behaviourist set up a situation where the behaviour is likely to occur naturally an only allow for there to be a limited number of responses and wait for the learner to pick the desired answer by choice or process of elimination and then they will be reinforced for choosing the correct answer, whereas the cognitive theorist belie ve in encouraging accommodation (learning information by placing it in a cognitive structure) and assimilation (forming or changing cognitive structures to holdShow MoreRelatedCognitive Psychology Definition Paper1387 Words   |  6 PagesCognitive Psychology Definition Paper Randy Strickland University of Phoenix PSY/360 Dione Johnson July 111, 2011 Cognitive Psychology Definition Paper Introduction Cognition is the â€Å"science† term for the process of thought.† Its usage varies in different ways in accordance with different disciplines: For example, in psychology and cognitive science, it refers to an information processing view of an individuals psychological makeup.
